Title: The Innovations of Chris J Vrettos

Introduction

Chris J Vrettos is a notable inventor based in Mentor, Ohio, with a significant contribution to the field of medical imaging technology. He holds four patents that showcase his innovative approach to enhancing CT scanner functionality and image reconstruction.

Latest Patents

One of his latest patents is for a CT scanner having multiple detector widths. This invention includes a radiation source mounted for rotation about a scan circle, featuring a ring of radiation detectors that consist of both narrow and wide detectors. The narrow and wide detectors are separately sampled and operated on with different digital filters. The wider detectors have a more limited frequency response, while the output signal from the narrow detector has a higher frequency response, resulting in better resolution. The filters are selected to yield an optimum signal-to-noise ratio, and when the data is merged, the resultant data achieves improved resolution compared to uniform width detectors.

Another significant patent by Vrettos is the prism architecture for CT scanner image reconstruction. This imaging system acquires data from a non-invasive examination of a subject and transfers it among various image processing agents on a data bus. The data acquisition agent generates subsequent agent locations and transmits them along with the image data. Various image processing agents perform imaging and processing operations on the data packets, ultimately leading to a display agent that communicates the processed image data to a man-readable image display.
